Buergersiochloa bambusoides

HABIT Perennial; caespitose. Rhizomes short. Culms 60–100 cm long. Leaves cauline. Ligule a ciliolate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate, or ovate; 6.5–27 cm long; 14–55 mm wide. Leaf-blade venation with distinct cross veins. Leaf-blade apex acute, or acuminate.

INFLORESCENCE Monoecious; with male and female spikelets in the same inflorescence. Synflorescence on a separate leafless culm. Inflorescence a panicle.

Panicle contracted; lanceolate; 7–21 cm long.

Sexes segregated; on unisexual branches; with male below. Spikelets solitary. Fertile spikelets pedicelled. Male spikelets pedicelled. Pedicels linear; pubescent.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 4–9 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; obtuse.

GLUMES Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume elliptic; 3–7 mm long; 1 length of upper glume; membranous; without keels; 3–7 -veined. Lower glume apex obtuse. Upper glume elliptic; 3–7 mm long; 0.75 length of adjacent fertile lemma; membranous; without keels; 3–7 -veined. Upper glume apex obtuse.

FLORETS Fertile florets female. Fertile lemma elliptic; 4–9 mm long; coriaceous; without keel; 5–7 -veined. Lemma surface pubescent. Lemma margins convolute; covering most of palea. Lemma apex acute; awned; 1 -awned. Principal lemma awn 5–30 mm long overall. Palea ovate; tightly convolute around flower; 1 length of lemma; coriaceous; without keels. Palea surface pubescent. Palea apex acute.

FLOWER Lodicules 3. Anthers 2–3; 1.2–4.2 mm long. Filaments united in a tube. Stigmas 2.

MALE Male spikelets distinct from female; 1 flowered; lanceolate; 2.7–4.4 mm long. Male spikelet glumes absent. Male spikelet lemma muticous, or awned (0–25mm).

DISTRIBUTION Asia-tropical: Papuasia.

NOTES Olyreae. Fijten.
